This invention relates to horns such as are attached to phonograplis orsimilar instruments for intensifying sound and throwing itin a desireddirection.

The object of the invention is to roduce a horn of simple constructionWlllOl may be folded so as to occupy a small space, enablin the horntehscoovenienily carried or packed for transportation... r

The. nvention consists in the construction and combination at partsto'be more'iull described hereinafter, and definitelyset fort. in theclaims. I

Reference is to be had to the accompairying drawings, forming a part ofthis specification, in wlnch similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of the horn, representing the same in itsopened or ex Fi 2 is a longitudinal vertical section of the rorn whenexpanded as inv Fig. 1, and Fig. 3 is a side elevation showing the hornin a folded or collapsed condition. 1

Referring more particularly to the parts, 1 represents the bodyof thehorn, which is preferably composed of leather, cioth, metal,

aper, or similar collapsible material. This liody has the same generalform as usually found in horns of this kind, comprising a oontractedneck 2, which attaches to a nipple or mouthpiece 3. As indicated, themouthpiece 3 is preferablyo'f conical form and should be constructed ofmetal or similar material. At the inner or large extremity of themouthpiece a lurality of ribs or stays 4 are attached ri d and these staspref erabl consist of at strips or bars 0 metal,

at sides whereof are attached longitudinally to the body- 1 of the horn.Near their outer extremities these stays 4 are connected by a pluralityof links 5, arran ed be-' tween the stays and pivotally attache therestest the oints 6, as will be readily'under stood.

. andf these'extend toward the mouthpiece 3 I and are attached to amovable ring or collar 9. TlllS collar 9 has preferably the form of aWhen the links 5' are all straightened out or extended, as indicated inFig. 1, they opcrate to maintain the metal frame of the device in itsmost expanded condition. The construction of the joints 7 is such thatwhen the horn-frame is opened out, asindicated, the horn will maintainitself in this open condition. When it is desired :to fold the horn, thering or collar 9 will be grasped and forced in the direction of theextremity of the mouthpiece. In this way the pull-rods 8 oper ate uponthe links 5 so as to reak the joints 7. In this Way theouter extremitiesof the stays or ribs 4 are brou httogether, and when completely foldedtie body 1' of the horn will collapse'so that the horn will presentsubstantially the appearance shown in Fig. 3. When in this condition,the horn may he veryconveniently carried about or packed for shipmentand may be readily opened out for immediate use when desired.

It should be observed that the metal parts of the horn when attachedtogether consti- I tute a light framework or frame givin the open hornthe required form. It 'shou d be understood that when opened outtheconnested links 5 constitut'e'a jointed ring completely encirclingthe bod of the horn.
